$BTC 1. Appears during the upward process, where the coin price fluctuates repeatedly at a high level.

2. By connecting the high points generated from the coin price's fluctuations at a high level with a curve, we get an upward convex arc.

This kind of shape is referred to as an arc top pattern.

The arc top pattern indicates that after a period of price increase, although the upward trend continues, the dominant bullish force driving the increase is gradually diminishing. The speed of the coin price increase slows down, eventually entering a state of stagnation. Later, the bearish force gradually strengthens, and the coin price begins to enter a slow downward trend, with the speed of decline gradually increasing. When people notice that the downward momentum of the coin price is forming, a clear arc shape appears at the top. Therefore, the arc top is also a kind of signal of a peak.
